Answer this question truthfully
### Question: What to expect if I have Tuberous sclerosis  (Outlook/Prognosis)?
### Response: Children with mild tuberous sclerosis usually do well. However, children with severe retardation or uncontrollable seizures usually do poorly. Occasionally when a severely affected child is born, the parents are examined, and one of them is found to have had a mild case of tuberous sclerosis that was not diagnosed.
The tumors in this disease tend to be noncancerous (benign). However, some tumors (such as kidney or brain tumors) can become cancerous.
